"Absolute data entry"
The transmitter has a calibrated mV display range. One absolute mV value is set with
a single buffer solution (adaptation of the measuring chain offset). A buffer solution
preferably with 225 or 475 mV is used.

INFO
Selection for calibration
(only two-circuit)
Select electrode 1 or 2, and then run through
calibration for each individual electrode.
Note in display
Display of the type of on-site calibration selected in the
calibration settings.
Entry of offset value circuit 1 / 2
Enter the mV value for the electrode offset (electrode
offset = deviation of the measured value display from
F
buffer solution mV value)
Confirm by pressing . The entered value is effective
immediately.
The maximum offset is 400 mV.
Note in display:
Error message if the entered offset leaves the
maximum range.
F
End of calibration
Accept: Pressing accepts the new calibration data.
Reject: The data is not accepted and the device has
not been recalibrated.
Recalibrate: The data is rejected and the device is
recalibrated.
Note in display:
If the electrode is back in the medium, so that
measurement can take place?
